What You Should Think About When Replacing Your Furnace

When it’s time to replace your furnace, there are a number of things you should consider before making a judgement on a particular replacement furnace. With your space and your family’s needs in mind, Morgner Inc. Air Conditioning & Heating can help you choose the furnace that will keep your home warm and comfortable.

Fuel Source
One of the first things you need to consider is which fuel source your new furnace will use. The majority of furnaces in North America use natural gas, but some residences are set up to use liquified petroleum gas, propane or even electricity. It’s important to know which type of fuel is needed for your new furnace.

Furnace Type
You’ll also want to decide which type of furnace you’d prefer to appropriately meet your needs. Furnaces are available in single-stage, two-stage or variable capacity models. A single-stage furnace blows heat consistently at one speed and isn’t the strongest in efficiency within these options. A two-stage furnace works well for many homes. Stage one of a two-stage furnace operates at about 65 percent of its capacity, and stage two will kick in for a heating boost on the coldest St. Louis days. However, if you want to go for the ultimate choice in flexibility and efficiency, a variable capacity furnace may be a good option.

Different from single- and two-stage models, variable capacity furnaces don’t have a set number of stages to go through to provide heat. A variable capacity furnace can actually operate at different capacities to answer your heating needs.

Zoning
Whether you want to factor in a zoning system with your replacement furnace is another thing to think about. You could save money by more efficiently using your furnace to heat the areas you typically use, rather than trying to keep the entire home at the same temperature. If you want more details about zoning possibilities for your home, Morgner Inc. Air Conditioning & Heating can help.

Size
Another key part of picking the best furnace for your home is making sure it’s the proper size for your house. If your furnace is too large for your home’s heating needs, it will waste a lot of energy incessantly cycling on and off. If your furnace is too small, it won’t be able to keep up on the coldest St. Louis days.

Efficiency
Last, but certainly not least, you need to check your furnace’s energy efficiency rating. A furnace’s efficiency is calculated by annual fuel utilization efficiency (AFUE). This rating identifies the ratio of annual heat output of the furnace compared to the total annual fossil fuel energy it consumes. For example, an 80 percent AFUE rating means that 80 percent of energy in the fuel heats the home and the other 20 percent gets out through places like the furnace venting. For a high-efficiency furnace, you’ll want to look for an AFUE rating of 90 to 98.7 percent.
